"How am I supposed to be inspired by that?"

A few days ago, Jan Visser of the Learning Development Institute (LDI) posted this on LDI 's Facebook page
Attached is a link to Paul Lockhart's "A Mathematician’s Lament." A brilliant plea, in my view, to refocus education on such things as beauty and to acquire one's knowledge of disciplines like math and science within the context of relevant current issues that can be seen, also, within a historical perspective. Not an entirely new viewpoint, of course, but it's very well formulated. Enjoy! JV
Jan's right, it's a great paper on why our teaching of mathematics puts kids off instead of showing them what's fascinating and beautiful about it. Although it's several years old now (first published in 2002) it remains relevant - unfortunately. Here are a couple of tasters...
A musician wakes from a terrible nightmare. In his dream he finds himself in a society where music education has been made mandatory. “We are helping our students become more competitive in an increasingly sound-filled world.” Educators, school systems, and the state are put in charge of this vital project. Studies are commissioned, committees are formed, and decisions are made— all without the advice or participation of a single working musician or composer.
Since musicians are known to set down their ideas in the form of sheet music, these curious black dots and lines must constitute the “language of music.” It is imperative that students become fluent in this language if they are to attain any degree of musical competence; indeed, it would be ludicrous to expect a child to sing a song or play an instrument without having a thorough grounding in music notation and theory. Playing and listening to music, let alone composing an original piece, are considered very advanced topics and are generally put off until college, and more often graduate school.
As for the primary and secondary schools, their mission is to train students to use this language— to jiggle symbols around according to a fixed set of rules: “Music class is where we take out our staff paper, our teacher puts some notes on the board, and we copy them or transpose them into a different key." ... educators soon realize that even very young children can be given this kind of musical instruction. In fact it is considered quite shameful if one’s third-grader hasn’t completely memorized his circle of fifths. ...

In the higher grades the pressure is really on. ...Students must take courses in Scales and Modes, Meter, Harmony, and Counterpoint. “It’s a lot for them to learn, but later in college when they finally get to hear all this stuff, they’ll really appreciate all the work they did in high school.” Of course, not many students actually go on to concentrate in music, so only a few will ever get to hear the sounds that the black dots represent. ... “To tell you the truth, most students just aren’t very good at music. They are bored in class, their skills are terrible, and their homework is barely legible. ... I guess there are just music people and non-music people. I had this one kid, though, man was she sensational! Her sheets were impeccable— every note in the right place, perfect calligraphy, sharps, flats, just beautiful. She’s going to make one hell of a musician someday.”
...Sadly, our present system of mathematics education is precisely this kind of nightmare. In fact, if I had to design a mechanism for the express purpose of destroying a child’s natural curiosity and love of pattern-making, I couldn’t possibly do as good a job as is currently being done— I simply wouldn’t have the imagination to come up with the kind of senseless, soul- crushing ideas that constitute contemporary mathematics education.
... By removing the process and leaving only the results of that process, you virtually guarantee that no one will have any real engagement with the subject. It's like saying that Michaelangelo created a beautiful sculpture without letting me see it. How am I supposed to be inspired by that?

BTW - the BEST mathematics book I have ever read is The Number Devil by Hans Magnus Enzensberger.
